Start Building the Tang Dynasty from Self-Deprecating Fiefdoms

In the fourth year of Zhenguan in the Tang Dynasty, Li Tai, a modern retired special forces soldier and top student, traveled through time with an emergency warehouse and became the fourth son of Li Shimin. Facing the frightening struggle for imperial power, in order to preserve his brother Li Chengqian's position as prince, and for the prosperous Tang Dynasty in his heart, he resolutely chose to devalue himself to his fiefdom and create a prosperous age for Li Tai! Li Shimin: What Tai'er did is better than my million-strong army! Queen Changsun: My son has such a broad mind, the Tang Dynasty is very lucky, and the people are very lucky! Li Chengqian: If the fourth brother is here, why worry about the instability of the crown prince's position? Aristocratic family: , what a monster! People: Lord Qingque, the Living Bodhisattva is reborn!
